BigInt Calculator
Arbitrary-precision math
Free
Work with numbers of thousands of digits without freezes or limits. All complex calculations are automatically accelerated by your device's GPU.
A calculator for those who need more than standard precision.
Works with integers and decimals of arbitrary size — no rounding, no overflow, no lost digits. Heavy operations are accelerated on the GPU via Metal, so even multiplying numbers thousands of digits long stays fast.

GPU acceleration
